Sleep Disturbances and Fatigue

Symptom Patterns Across Populations
General Population and Young Adults
In the general population, about a quarter to a third of individuals report symptoms of common mental health disorders, with women and younger adults more likely to experience anxiety and depression. These symptoms are associated with a lower quality of life and increased risk of suicidal ideation Saunders2024Werlen2020Witteveen2023.
Healthcare and Other Professionals
Among healthcare workers and other professionals, symptoms such as nervousness, fatigue, sadness, and sleep problems are prevalent, especially during periods of high stress or work overload, such as the COVID-19 pandemic Silva2025Oliveira2023.
Athletes and High-Performance Groups
Elite athletes and professional footballers also report high rates of distress, anxiety/depression, sleep disturbances, and adverse health behaviors. These symptoms are often linked to career dissatisfaction, injuries, and stressful life events Gouttebarge2015Gouttebarge2015Gouttebarge2019.
Overlapping and Co-Occurring Symptoms
Symptoms of depression and anxiety are highly interrelated and often co-occur with other disorders, such as post-traumatic stress disorder (PTSD). Key overlapping symptoms include inability to relax, persistent negative mood, and diminished positive emotions .
Conclusion
Common mental health disorders are marked by a cluster of symptoms—nervousness, sadness, fatigue, sleep problems, and distress—that frequently overlap and co-occur. These symptoms are prevalent across various populations, including the general public, healthcare workers, young adults, and athletes. Recognizing these core symptoms is essential for early identification and effective intervention.
